Andrew,

Another issue.
The zorder of the spine artists is set to 0 by default.
I notice that you're changing the zorder of its artist attribute, but
note that it has no effect as what matter is the zorder of the spine
itself.

As a related issue to what John mentioned, I think one option you can
do is to derive the Spine class itself from a real artist class,
rather than the base "Artist". With this, you don't need to implement
all other set/get method, e.g., color, etc. For example, you may
derive it from the Patch class. Note that while the Patch class is
intended for closed path, you can stroke a straight line with it.

Regards,

-JJ

The 0.98.5.3 binaries have a problem with the PNG output, so I pulled
them.  Charile, do you still have the 0.98.5.2 win32 binaries to
reupload while we are sorting out this problem?

Hello,

Few days ago there were new windows binaries on Sourceforge - version
0.98.5.3. Yesterday I also found them in Google cache (see the
attachment - I am interested mainly in Python 2.6).

But they are not now on Sourceforge. Is there a good reason for it
(for example there could be problematic)? Or is it a Sourceforge
mistake (I am not sure but I think that design of the Sourceforge
download page was different)?

Maybe there is another explanation - but if it is possible, could
windows binaries be uploaded again?

Thank you,
Petr Marhoun
